摘要

The authors wish to thank the discussers for their interest in our paper and for their suggestions. The first method advocated by the discussers is what the authors used in the paper. The second method suggested by the discussers was to use a cylindrical cavity expansion model, proposed by Jiang and Shen, to consider the softening behaviour of a dilative soil. They consider that the second method can be used to analytically calculate the stress and strain distributions in the soil surrounding the soil nail, but did not show how it can be used in soil nail pullout analysis.rnIt should be noted that the actual stress and strain distributions in the perimetric and axial directions around the soil nail are not uniform (see Fig. 2 in the paper for the former case). In the axialrndirection the soil nail pullout resistance is developed in a progressive way, as in the simple method proposed by the authors. In addition, the proper evaluation of the model parameters, for example how the elastic and plastic regions along the soil nail are defined, is also important in the development of the new method.
